The art style in the manga can influence how the characters are perceived. In the Masamune Kun's Revenge manga, the character designs can give a certain impression that might be different from what you imagine while reading the light novel. Moreover, the light novel can use language more flexibly to create a mood. For example, it can use long, descriptive passages to build suspense, while the manga may use panel arrangements and visual effects to achieve a similar effect.
The manga often has more visual impact. It can show the characters' expressions and actions vividly. The light novel, on the other hand, might have more detailed descriptions of the characters' inner thoughts and the overall world - building. For example, in the light novel, we might get a more in - depth exploration of Masamune's motivation for revenge, while the manga can show his cool and confident look more directly through illustrations.
One difference is the pacing. The manga may speed up or slow down the story to fit the visual narrative. In contrast, the light novel can have a more consistent pacing in terms of the written story. Also, the manga might cut out some minor details that are present in the light novel for the sake of simplicity. For instance, some of the more complex explanations about the school's hierarchy in the light novel could be simplified in the manga.
